Works great with iphone. This is better than similar 5000mah batteries as it shows the battery state along with the iphone battery state on the iphone screen as it starts to charge.

Hi Borderlands, Sorry to hear both of your units were damaged after a fall. This model isn’t designed for heavy impact, and it sounds like the durability didn’t meet your needs. Appreciate you sharing your experience.

It works well. But it doesn’t last as long as it says it does. And it’s also missing the power button.

Hi Hayden, I’m glad the power bank works well for you. Your feedback on battery life and the design is helpful for improving future products. This model does include a power button—it’s located on the side of the unit and is used to turn the device on, off, or to switch modes (press twice to power off). If it seems missing or unresponsive, the unit may be defective. Please contact our support team for help with inspection or a replacement:

I really like this portable charger. The slim metal design makes it easy to carry in a bag or pocket, and the magnetic feature connects securely to my phone without needing extra cables. It charges quickly and the LED display is helpful for showing the remaining battery level. The 5,000mAh capacity is perfect for giving my phone a quick boost during the day when I’m away from a charger. It’s well made, lightweight, and very convenient for travel or everyday use. I would definitely recommend this power bank to anyone looking for a reliable and portable charging option.

Bought it on sale and have used it during travels. It’s small and fits anywhere. Charges my 15Promax quickly. Only complaint is that it tends to heat up, which i guess is expected with Qi based chargers.

Slim, lightweight, well-built. I avoid mystery brands on these things, since it's going to live in my pocket. Solid brand name, lightweight, slim and excellent build quality. I don't even notice I am carrying it. The dual USB A/C outputs are a major plus, making this a versatile little unit
